Abstract:
The new tetradentateunsymmetrical Schiff base ligands and VO(IV) complexes were synthesized and characterized by using IR, UV–Vis and elemental analysis. The electrochemical properties of the van-adyl complexes were investigated by means of cyclic voltammetry. The oxidation potentials are increased by increasing the electron-withdrawing properties of functional groups of the Schiff base ligands according to the trend of . The thermogravimetry (TG) and differential thermoanalysis (DTA) of the VO(IV) complexes were carried out in the range of . The complexes were decomposed in two stages. Also decomposition of synthesised complexes is related to the Schiff base characteristics. The thermal decomposition of the studied reactions was first order.
